Saturated Steam Calculator

Understanding steam properties is crucial in numerous engineering and industrial applications, especially when working with boilers, turbines, and heating systems. The Saturated Steam Calculator is a powerful, easy-to-use tool designed to compute key saturated steam properties such as saturation pressure, temperature, specific volume, enthalpy, and entropy based on user input. Whether you’re an engineer, technician, or student, this tool helps you quickly obtain critical steam data for your projects and calculations.

What Is the Saturated Steam Calculator?

The Saturated Steam Calculator is an interactive utility that determines the thermodynamic properties of saturated steam by accepting either pressure or temperature as input. It utilizes established steam tables (based on the IAPWS IF-97 standard) and linear interpolation between known data points to estimate values accurately.

By inputting a known steam property (pressure or temperature), the calculator returns corresponding saturation temperature or pressure and other essential properties like:

• Specific volume (vg)
• Enthalpy of saturated liquid (hf) and vapor (hg)
• Entropy of saturated liquid (sf) and vapor (sg)

• Entropy of saturated vapor (sg)

Step 5: Copy or Share Results (Optional)

You can copy the results to your clipboard or share them directly using the available buttons.

Step 6: Reset Calculator (Optional)

To start a new calculation, simply press the Reset button.

Practical Example: Calculating Steam Properties at 5 Bar Pressure

Suppose you want to find the saturated steam properties at 5 bar pressure.

• Select Pressure as the input property.
• Enter 5 in the pressure field.
• Click Calculate.

The calculator uses steam tables to interpolate and shows results such as:

• Saturation Temperature: approximately 151.86 °C
• Specific Volume (vg): 0.3744 m³/kg
• Enthalpy of liquid (hf): 640.09 kJ/kg
• Enthalpy of vapor (hg): 2748.7 kJ/kg
• Entropy of liquid (sf): 1.9370 kJ/kg·K
• Entropy of vapor (sg): 6.7659 kJ/kg·K

This data is essential for designing and analyzing steam-based systems at that pressure level.

FAQ: Saturated Steam Calculator

1. What is saturated steam?
Saturated steam is steam at the temperature where it is in equilibrium with liquid water at a given pressure, containing no superheat.

2. Why is it important to know steam properties?
Steam properties help design, optimize, and troubleshoot thermal systems like boilers and turbines.

3. Can I use the calculator for superheated steam?
No, this tool only calculates properties for saturated steam.

4. What units does the calculator use?
Pressure in bars, temperature in degrees Celsius, volume in m³/kg, enthalpy in kJ/kg, and entropy in kJ/kg·K.

5. How accurate are the results?
Results are approximate and based on standard steam tables (IF-97). They are suitable for general engineering but should be verified for critical applications.

6. What happens if I enter values outside the table range?
The calculator extrapolates using the nearest available data but accuracy may reduce at extreme values.

7. Can I input negative pressure or temperature?
No, only positive values are accepted as physically valid.
